"A man whom I certainly took to be a German—a man who talks German fluently."

"Middle-sized—with a beard—and dark eyes?"

"Yes," I said confidently; for somehow or other I began to feel singularly sure of these features.

"Of course I know who you suspect," she said, looking up suddenly. "And you had him removed from the island afterwards."

"You mean O'Brien? Yes, I did suspect him—though, mind you, I had nothing to go on. Do you know if he talked German?"

"He once told me he did, but I never heard him, and I didn't believe him."

"Why not?"

"One couldn't believe half he said, and I don't think he intended one to.
He was very Irish. But I don't believe he was the man."

"Why not?" I asked again.
